在 php 中不起作用的变量和会话变量包括

Question

OK.. forgive me, there are a couple similar questions posted already with the correct responses... I knew someday I would have to ask the people of the internet for help but I never thought it would be something so stupid...

here is my code.. so far..

index.php:

include "http://www.mywebsite.com/shared.php";
$page = "homepage";

include "http://www.mywebsite.com/htmlheader.php"; //trying to use "page" variable in here
echo ("<br>test2: " . $_SESSION['test']);
include "http://www.mywebsite.com/htmlfooter.php";

shared.php:

session_start();
$_SESSION['test'] = "what the f_ck im scared";

htmlheader.php:

echo ("test1: " . $page . "<br>" . $_SESSION['test']);

Output right now is:

test1:

test2:

(so the pages are being included.. just not able to use the variables..) From what I understand in its current state this should be printing something like:

test1: what the f_ck im scared

test2: homepagewhat the f_ck im scared

..The funny thing is I was not having any issue with the include using the variable. I had added some things but then it randomly stopped working so I reduced it down to this to try and figure out what the problem was.. I am assuming I have made some silly mistake.

Answer 1

Ensure that you have started the session with session_start();

also check whether allow_url_fopen or allow_url_include or both have been set to 0 (disabled) in php.ini. if yes try to activate it

include "htmlheader.php";

instead of

include "http://www.mywebsite.com/htmlheader.php";

Answer 2

ensure you have session_start(); at the top of the page that is including the includes
